Abstract
A system and method for monitoring engine operating data include monitoring various engine operating parameters and periodically storing engine data when corresponding criteria are met. In one embodiment, enigne operating parameters may include engine speed, powertrain demand, or a fluid temperature, for example. Engine operating data such as oil pressure, turbo boost pressure, battery voltage, fuel economy, oil temperature, coolant temperature, maximum RPM, maximum vehicle speed, and throttle position sensor voltage, for example may be stored for trending and analysis. In addition, engine components may be monitored to determine service or replacement.
